DETAILED DESCRIPTION

The example embodiments of the present disclosure are described below in combination with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as only an example. Therefore, those of ordinary skill in the art should recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted from the following description.

In the present disclosure, unless otherwise specified, the terms “first”, “second” and the like are used to describe various elements and are not intended to limit the positional relationship, temporal relationship or importance relationship of these elements. These terms are only used to distinguish one element from another element. In some examples, a first element and a second element may point to the same instance of the element, and in some cases, based on the context description, they can also refer to different instances.

The terms used in the description of the various examples in the present disclosure are only for the purpose of describing specific examples and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element may be one or more. In addition, the term “and/or” as used in the present disclosure covers any and all possible combinations of the listed items.

In the related art, in the case that the retrieving data involves with a short text, it usually may not possess a sufficient context and may lack a rigid grammatical structure, which might lead to difficulties in the intention recognition for the retrieving data. In addition, the intention recognition usually needs to be fine-grained, so that the user requirements can be classified in details. The properties of the short text would make it difficult to perform such fine-grained intention recognition. In particular, for certain highly professional retrieving data, such as the medicine-related retrieving data, it is not only necessary to analyze that the retrieving data is about a medication query, but also to distinguish whether the user specifically needs the medication guidelines, the contraindications, the drug price comparison, etc. In this case, labelling these fine-grained intentions often requires participation of the highly professional personnel, such as medical experts. However, this may lead to a large consumption of time and cost. Therefore, for these highly professional retrieving data, there is often a lack of corresponding labelled data or only a small amount of labelled data is involved, which is not beneficial for the subsequent training of a model for short text classification.

Aiming at the above problems, a method for data processing is provided according to an aspect of the present disclosure. The embodiments of the present disclosure will be described in detail below in combination with the accompanying drawings.

FIG. 2 shows a flow diagram of a method 200 for data processing according to an embodiment of the present disclosure. As shown in FIG. 2 , the flow diagram of the method 200 according to the embodiment of the present disclosure includes the following steps:

S202, first retrieving data associated with a first user and a first retrieving result selected by the first user from at least one retrieving result corresponding to the first retrieving data are obtained, wherein the first retrieving data is labelled with an intention tag indicating a retrieving intention of the first user;

S204, second retrieving data that is used by a second user to conduct retrieving and selecting the first retrieving result within a predetermined time period is obtained; and

S206, the intention tag is assigned to the second retrieving data.

According to the method for data processing of the present disclosure, in consideration of the fact that the users selecting the same retrieving result are supposed to have the same retrieving intention, assuming that the retrieving intention of the first user for selecting a certain retrieving result to conduct retrieving through the first retrieving data is known, if the other second user selects the same retrieving result during his retrieving, it implies that the second user should have the same retrieving intention as the first user. By tracking the second retrieving data used by the second user to conduct retrieving, it may have the same intention tag as the first retrieving data. Therefore, a large amount of retrieving data labelled with the retrieving intention can be generated or created, and thus data enhancement of the training data can be achieved. In addition, the process of data enhancement does not rely on a traditional natural language processing mode (such as synonym replacement, noise adding, random word adding and deleting, etc.), and thus the diversity of the data can be improved.

In step S202, the first retrieving data that have been used by the first user and the first retrieving result selected by the first user from the corresponding at least one retrieving result may be obtained. For example, the first retrieving data may come from a certain user A. The process that the user A conducts retrieving on the first retrieving data through a search engine (such as the search engine developed by Baidu company) may be recorded and retained by the search engine. Assuming that the first retrieving data is a retrieving statement such as “what medicine should be taken for headache”, at least one retrieving result may be generated after retrieving through the search engine. Accordingly, the retrieving result selected from the at least one retrieving result by the user A may also be obtained through the search engine.

Herein, the first retrieving data may be a piece of retrieving data, or may be a retrieving data set including a plurality of pieces of retrieving data, and its number is not limited in the present disclosure. In the case that the first retrieving data involves with the retrieving data set, the retrieving data included therein may come from different users, for example, from a user B, or a user C, etc., which is different from the user A. Accordingly, the obtained retrieving result also corresponds to the above individual users. These retrieving data may be associated with each other, or may not have any correlation with each other. In addition, in the case that the first retrieving data involves with the retrieving data set, the data volume of the retrieving data included therein, however, may be small. This is because for certain highly professional retrieving data, such as the medicine-related retrieving data as described above, the data volume may be inherently small since the labelling may lead to a large consumption of time and cost.

In addition, the first retrieving data may be the retrieving data that have been labelled with the retrieving intention. That is, the first retrieving data may have the intention tag, which may be used to indicate the retrieving intention of the first user.

According to some embodiments, the first retrieving data may be a text or an image. In this way, the data enhancement of various data can be achieved by utilizing the text searching and image searching functions provided by the search engine, such that the method of the present disclosure is not only suitable for the text-type data, but also can be extended to the image data.

In the case that the first retrieving data involves with the text, it may be in the form of a retrieval statement composed of a complete sentence, or may be in the form of retrieving words composed of a plurality of discrete words. For example, the first retrieving data may be a retrieving statement such as “what medicine should be taken for headache”, and may also be retrieving words such as “headache medicine taking”. Accordingly, the intention tag may indicate the retrieving intention about the medication query of the user. As a reference, for the medicine-related retrieving data as described above, there may be quite a lot fine-grained retrieving intentions involved, for example, a dozen of fine-grained retrieving intentions may be involved. In addition to the aforementioned retrieving intention about the medication query of the user, other retrieving intentions about e.g. the medication guidelines, the contraindications, the drug price comparison and so on may be included.

In the case that the first retrieving data involves with the image, it may be in the form of the image. That is, this situation may correspond to a function of “search by image” provided by the search engine. For example, the first retrieving data may be a picture about a Labrador dog. Accordingly, the intention tag carried by the first retrieving data may indicate a retrieving intention of the user about inquiring the dog type.

According to some embodiments, the at least one retrieving result includes at least one web link obtained by conducting retrieval on the first retrieving data. Taking an example that the first retrieving data of the user A is “what medicine should be taken for headache” as described above, a plurality of retrieving results, i.e., web titles that have respective web links, may be displayed on an interface of the search engine through the retrieving. Therefore, the web link clicked by the user A among these displayed retrieving results can be obtained.

A principle utilized in the present disclosure is set forth here. Assuming that the users clicking the same web link have the same retrieving intention, in the case that a web link clicked by the user A with the known retrieving intention is obtained, if another user, such as a user X, clicks the same web link as well during the retrieval, it indicates that this user should have the same retrieving intention as the user A. In this case, if the retrieving data used by the user X to conduct retrieving is traced back, it may have the same intention tag as the first retrieving data. Thus, a large amount of retrieving data labelled with the retrieving intention can be generated or created.

Therefore, with the aid of the web links, the traceability of the retrieving data used by the second user to conduct retrieving is provided, which in turn provides a basis for the implement of the subsequent data enhancement.

According to some embodiments, the first retrieving result includes a web link selected by the first user for the first time or for the last time from the at least one web link.

Since the retrieving result is usually displayed in the form of a web title on a page of the search engine, where the web title may often reflect the actual retrieving intention of the user accurately, the retrieving result selected by the user for the first time or for the last time may be considered as an optimal retrieving result that best reflects the retrieving intention of the user. Therefore, the retrieving data with the accurate intention tag can be obtained.

In step S204, the principle as described above is utilized as follows: assuming that the users clicking the same web link have the same retrieving intention, if the retrieving data used by another user who clicks the same web link is traced back, it may have the same intention tag with the first retrieving data.

Similar to obtaining the first retrieving data and the first retrieving result of the first user, the corresponding retrieving data, i.e., the second retrieving data that is used by the second user to conduct retrieving may also be crawled through the search engine.

The predetermined time period may be set according to actual conditions, such as three months. Considering that the web links may have a situation of expiration over time, a length of the predetermined time period may be properly adjusted. For example, the retrieving data, such as “what are the medicines for relieving headache” that is used by the user X, who clicks within three months the retrieving result (i.e., the web link) selected by the user A, may be crawled through the search engine.

In step S206, since the second retrieving data having the same retrieving intention as the first retrieving data in step S202 are obtained through step S204, the intention tag of the first retrieving data may then be assigned to the second retrieving data, so that a large amount of retrieving data labelled with the retrieving intention can be generated or created.

According to some embodiments, assigning the intention tag to the second retrieving data may further include determining whether the second user and the first user are the same; and in response to determining that the second user and the first user are not the same, labelling the second retrieving data with the intention tag.

In this way, the retrieving data used by the second user that is different from the first user can be obtained in the first place, so that diversified retrieval expressions that are used by these different users who have differences in aspects such as a personal background and an educational status etc. are utilized, thereby bringing even more data diversities to improve the data enhancement effect.

According to some embodiments, the first retrieving data and the second retrieving data may be combined as training data for training a classification model. Therefore, a large amount of retrieving data labelled with the retrieving intention can be generated or created.

Here, the classification model may be, for example, a model for short text classification. The present disclosure does not limit the types of the neural networks adopted by the model. For example, it may be a deep neural network model.

As described above, according to the method for data processing of the present disclosure, in consideration of the fact that the users selecting the same retrieving result are supposed to have the same retrieving intention, assuming that the retrieving intention of the first user for selecting a certain retrieving result to conduct retrieving through the first retrieving data is known, if the other second user selects the same retrieving result during his retrieving, it implies that the second user should have the same retrieving intention as the first user. By tracking the second retrieving data used by the second user to conduct retrieving, it may have the same intention tag as the first retrieving data. Therefore, a large amount of retrieving data labelled with the retrieving intention can be generated or created, and thus data enhancement of the training data can be achieved. In addition, the process of data enhancement does not rely on a traditional natural language processing mode (such as synonym replacement, noise adding, random word adding and deleting, etc.), and thus the diversity of the data can be improved.

FIG. 3A and FIG. 3B show schematic diagrams used to illustrate a method for data processing according to an embodiment of the present disclosure.

FIG. 3A exemplarily shows an example of retrieving data 310 “what medicine should be taken for headache” associated with the user A and a selection of a retrieving result 313 from a plurality of retrieving results 311 to 314 by the user A. As shown in FIG. 3A, the plurality of web links 311 to 314 obtained through retrieval are shown, among which the web link 313 is the web link that is clicked by the user for the first time. As described above, the retrieving data 310 has been labelled with the intention tag for the retrieving intention of the user A. For example, the intention tag may indicate the retrieving intention of performing the medication query of the user A.

FIG. 3B shows a retrieval history of the user B who clicks the same web link 313 within three months, which is crawled through the search engine. As shown in FIG. 3B, retrieving data 320 used by the user B who clicks the same web link 313 to conduct retrieving is “what are the medicines for relieving headache” as shown. That is, the user B clicks the web link 313 from the plurality of web links 321, 313, 322 and 323. Therefore, the retrieving data 320 of the user B and the retrieving data 310 of the user A may be made to have the same intention tag. The intention tag may indicate the retrieving intention of performing medication query of the user B.

In this way, more retrieving data labelled with the retrieving intention, such as the retrieving data 320, can be generated or created based on the retrieving data 310 labelled with the retrieving intention associated with the user A, so that the data enhancement of the training data is achieved. In addition, the data enhancement process does not rely on a traditional natural language processing mode (such as synonym replacement, noise adding, random word adding and deleting, etc.), and thus the diversity of the data can be improved.
